IPROPELLINGr-WHEEL.

Specifcaton of Letters Patent No. 32,182, dated April 30, 1861.

To all whom it may concern:

Be it known that we, Cicnao CoMsToon and CARLOS GLIDDEN, of the city ofMilwaukee, in the State of Wisconsin, have invented certain new anduseful Improvements in Propelling-Wheels; and we do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings and to the letters and marksthereon. y

Our invention relates to that class of propelling wheels usuallydenominated feathering wheels, and the improvement made by ushasreference to the means for giving motion to the paddles and forsteadying and guiding them while in operation.

Of the drawings forming part of this specification Figure 1 is aphotographic perspective view of wheel. Fig. 2 shows the side view ofthe wheel, the main shaft the arms, the cam, and the cam groove, thelevers and friction wheels, the guard or safety chain, the guide lugsthe journals on which the friction wheels revolve, the paddle and paddleshafts, also the form and position of the cam, when the levers of acertain length are on a line with the face of paddles. Fig. 2a shows theside View of wheel, the main shaft &c. as above mentioned, the form andposition of the cam, when the levers of a certain length are at rightangles with `the face of paddles, either or both cams giving the sameposition to the paddles. Fig. 3 shows the end view of wheel, the face ofpaddles the paddle shaft and the edge of the guard or safety chain; Fig.4, view of paddle, shaft, bracket lever and friction wheels; Fig. 5 sideview of friction wheels and levers.

A is the main shaft; B radiating arms; C rotating paddles; D paddleshafts; E levers attached to paddle shafts, and may be placed on adirect line with the face of the paddles, or at any angle desired, ortwo levers on each paddle shaft at the same or different angles, and thelength of the lever or levers, and it or their position or angle, withthe face of the paddles, and the desired position of the paddles,governs the size, form, and position of the cam; F stationary cam; Grgroove in stationary cam in which the friction wheels revolve; I-I thefriction wheels revolving in groove of cam; I, journals on the outer endof levers on which the friction wheels revolve; J, guard or safetychain; K, guide lugs, regulating the action of safety chains; the safetychain and its lugs, control the levers when they are near or on a directline drawn from center of main shaft, through the center of paddleshaft; L brackets on paddle shafts, arranged to raise or lower thepaddles; M, bolts securing paddles to brackets.

The advantages of feathering wheels are so well known that it is notdeemed necessary to set them forth here. One of the objections whichhave been urged against them, that they can not be made as strong anddurable as thew rigid or fixed paddle wheel, it will be seen does notbear upon our improvement. lVhen in operation the paddles "of this wheelwill always be fully supported and sustained.`

It will be perceived that by the means here shown and named the paddleswill enter and leave the water in vertical position or nearly so, andthat they will be effectively held in the vertical position during theperiod of time when they are acting upon the water and propelling thevessel.

This wheel is susceptible of being used with excellent effect as anundersliot mill wheel, or as a current wheel. Instead of having oneseries of friction rollers traversing in the cam groove two series ofsuch rollers may be used in connection with a cam flange, the ange beingembraced between the rollers.

In some instances it may be desirable to use two levers to each paddle.

That we claim as our invention and desire to secure by Letters Patent,is-

l. Feathering the paddles by means `of the lever rigidly attached to theaxle of the paddle and having friction rollers which March 1861.
